Why is one of my 5 week old cuckoo marans comb a little bigger than the other one?

One of my Barred Rock has compact comb, and the other one has loose danglily comb.

Here are the pictures of my two 5 week old chicks

I attached my pictures

They both look like pullets.

It's not looking really big, I think it's a pullet.

Ok thanks! I hope so all the rooster other than one have been really mean and chased people and it’s aggravating having to take them to the sale
